Precautions for installation of air cooler

Please select a stable foundation before installing the air-cooled water chiller. The surrounding air is unblocked, the air is free of pollution and there is little oil pollution. The canopy shall be more than 1.5 meters above the machine platform.

If the surrounding air is still hot during use, please install an exhaust fan to maintain air convection, or use the exhaust pipe to exhaust the hot air to the outside, which will not only increase the service life of the chiller, but also improve efficiency and reduce costs.

The ambient temperature during installation should be below 35 ℃ to ensure that the machine is effective. The power supply, load and grounding parts shall be constructed in accordance with relevant laws and regulations.

The first operation must check whether the following items are correct:

1. Whether the power supply voltage and phase number meet the model and specification, please refer to the nameplate.

Note that the power supply of the water chiller above 3HP is three-phase, the voltage is 380-415V, the phase of the 50HZ power supply is RST, the neutral line (zero line) is N, and the ground line is E.

2. Whether the make-up water inlet has been connected to the pipeline, and the water source shall not be closed

3. Fill the ice tank with water before starting the water pump.

4. Turn on the water pump switch. At this time, please note that the ball valve at the inlet and outlet of chilled water must be opened.

5. Please pay attention to whether the water pump and fan motor run in reverse direction. If the connection is reversed, any two power bit lines must be exchanged and then closed.

6. Finally, turn on the compressor switch and the compressor and fan will run automatically. Please check and adjust the required temperature.

7. Please shut down the machine in reverse order.
